PROPOSAL Civic Center StorrnwaterLi fTStationRenovation Design Services address both capacity limitations and operation and maintenance issues. Michael Baker then completed final design of the selected upgrades which consist of, • Removal of three (3) existing VFDs and installing four (4) now PowerFlex 753 VFDs. • Installing new wiring between new VFDs and new motors. • Installing additional digital input and analog output card for PLC • Removal of existing in-line grinder electrical distribution and control panel and wiring, • Removal of three (3) existing pumps and motors and install four (4) new vertical shaft driven dry pit screw type pumps and motors equipped with flywheels. • Removal of three (3) existing in-line grinders and installing 8 -inch diameter suction pipe and eccentric reducers at all four (4) pump locations. • Removal of existing 4 -inch and 6 -inch discharge pipe and valves at three (3) pump locations and replacement with 8 -Inch diameter discharge pipe, plug valves and eccentric reducers at all four (4) pump locations. • Removal of existing 6 -inch swing check valves and replace with 8 -inch non -slam rubber flapper swing check valves. 3 ,'ta', Reconstruction of the Los Alamitos Pump Station and Retarding Basin 6 Orange I Los Angeles Counties, CA Client: County of Orange, 300 North Flower Street, Santa Ana, CA 92703 Reference: Mr. James Volz, Principal Engineer, (714) 647-3904, jpmes voizCo2ocpw occ.v.com Year: 2014 (Construction) Team Members involved: Sal Sheikh (Structural Engineer), Fabio Sanchez -Duran (Structural Engineer), Karl Meier (Project Engineer); Yee Ping See (Electrical Engineer) Michael Baker provided preliminary and final design, construction support, and commissioning services for the design of a new 800 -cubic -feet -per -second (516 MGD) stormwater pump station with engine -driven pumps to replace an existing pump station facility. The original Los Alamitos Pump Station was constructed in 1958 to pump storm water from low-lying marshlands up to the San Gabriel River. Pump Station. The pump station includes four (4) vertical mixed flow pumps with a design capacity of 129 MGD. Each pump is driven by a 1500 hp dual -fuel engine (natural gas and propane). Engine related components include a compressed air starting system, primary and secondary jacket water cooling system, natural gas primary fuel system, and propane back up fuel system. The pump station also includes a low -flow pump station with submersible pumps in a separate wet well with a total capacity of 5 MGD. Force Main Rehabilitation and Condition Assessment. Each pump discharges into a new 54" force main, which connects to a rehabilitated 54" force main that siphons under the Haynes Steam Plant intake open channel, and discharges to the San Gabriel River. The existing force mains were originally RCP. As part of the project, a condition assessment was performed including a INY91tN M1YltlNA4 - 13
